Wyoming 1880. Childhood sweethearts Rose McKinley and Will Hyde have always been destined to marry, and with their parents just as keen on the match, there is nothing to stop them. Except perhaps Cora, Rose's younger sister. Lovesick and hung-up on Will, she is sick of the happy couple. So when the handsome Mr Galloway comes to town and turns Rose's head, Cora sees an opportunity to get what she wants – Will.
